Network Connection Problems

[Greg0145]

Strangest problem I have ever seen. Received computer, many viruses,
malware, spyware. Cleaned, ran additional scans, found nothing.
Computer will connect to the Internet after a reboot, but cannot after
5 - 10 minutes, varies. Computer can ping any web address, not just
IP. So I CAN ping yahoo.com and get a response. Link lights are on and
good. Nothing has changed with DNS, Default Gateway, IP address,
Subnet Mask. I have put this computer on two differnet routers, same
problem on each.

Something very weird. If I disconnect the CAT5 cable from the router
for just a split second and then reconnect the computer can get online
again, but again, after 5 - 10 minutes it cannot.


I have uninstalled and reinstalled IE several times. Did a repair form
the XP disk (reinstalled all system files). Nothing helps.


Alos note it is not just IE. After the internet loses connectivity, I
cannot update any Antivirus programs or spyware programs (search for
updates). However, I CAN still ping.


I have tried getting to the router browser after loseing connectivity,
will not connect. Again, after a reboot or unplugging the CAT5 cable I
can.


If anyone has any idea what may be going on with this PC let me know.
I've tried everything I know to do.

the netsh command in SP2 can rebuild the Winsock catalog. Open the command
prompt and type:
netsh winsock reset catalog
then press ENTER.

I don't have the pc with me but will try this first thing tomorrow. Can you
explain why the internet works at first but then quits? I've read other post
where this did not fix the problem. Not that I don't think it can I'm just
trying to figure out what is happening for future reference. Also, it's not
just port 80, the problem also affects several others, such as port 8800 and
8801, which a sharing program uses to share Outlook data between computers.

down again.

Anyone know of any other rememdy???

Have you tried LSPFix? It sometimes fixes problems caused by improper
un-installs of malware and viruses.

Try the "Winsock Repair" http://pcbutts1.com/downloads/tools/tools.htm it is
not the same command that Mark told you but similar.
